    Review Samsung Galaxy S4

    Not uncommon for the "on paper" certain devices cause the interest due to the attractive design and balanced performance, but live is that the design is the only thing that they have. With the Samsung devices are often diametrically opposite situation. On the screen design seems bored, and features the same as the others, but at a closer look you notice that things do not work just as you'd expect, and even a little bit better. This applies to everything - the interface, cameras, autonomy, tactile sensations, and so on. Finally, to assess the Samsung Galaxy S4, not enough to look at the pictures with his picture and read about the opportunities it has to be seen live. Yet no one, used the device in hand, remained indifferent, and those who also knows what opportunities there are embedded, and does have to face the fact that to compete with the Samsung becomes harder and harder. Our readers have already had the opportunity to see the smartphone video review, today we offer a text review Samsung Galaxy S4.

    Despite the fact that the smartphone is different from the one that we have visited in the video, it is not commercial. The final version of the Samsung Galaxy S4 may have a different set of installed applications and interface.

    Design and ergonomics

    As mentioned in the video, the design closer to the Samsung i9500 Samsung Galaxy Grand Duos and Samsung Galaxy Premier, rather than to the Samsung i9300. This is facilitated by the flat back of the case and its sides, and the "volume" button Home. In addition, the plastic is now no invoice "under the metal", it is more like LG Nexus 4 and LG Optimus G, with the only difference being that they use glass pattern is under it, while the Galaxy S4 main body material - polycarbonate (plastic). However, this simple design gives the body a smartphone that same flavor, without which he would have become another white device.

    Build quality is excellent and the fit of parts, taking a smartphone in hand, you realize that you keep an expensive device, even without a cooling of the metal arm or slippery glass. Taking into account the fact that the new product is equipped with a large 0.2-inch (half a centimeter) screen, smaller than the width of a smartphone even predecessor, 6.98 cm vs. 7.06 cm, respectively. Changed for the better thickness and weight - 7.9 mm vs. 8.6 mm and 130 g versus 133 g and only the height remained the same - 136.6 mm, with all this, in addition to the long diagonal of the display, the smartphone is equipped with a more capacious battery. Now its capacity is 2600 mAh, whereas the Samsung Galaxy S3 was 2100 mA * h It is these little things and develops the overall favorable picture of the device. All a bit smaller and with a little bit better. Note that the decrease in the thickness had no effect on the camera module, on the contrary, instead of 8 MP in the Samsung Galaxy S3, Galaxy S4 owners will have at their disposal 13 MP trend.

    Those who are confused by the number of holes in the top of the front panel, can look towards the smartphone in the dark blue body color. We also note that the number of sensors actually rolls over, all nine of them, they are used to control the smart phone and get different data. In addition to the visible elements in the upper part of the body is the one that becomes visible only when certain events, whether it's a missed call, message, or email message from Facebook - LED, flashing different colors.

    The operating system and shell

    Smartphone Samsung Galaxy S4 first device, having been in our hands running under the Android operating system version 4.2.2. It also uses the latest version of the shell TouchWiz, which is easy enough to find, despite the fact that it is very much of it is completely different. In the future, the same interface will sport Galaxy S3, Note II and a number of other devices. The main difference between the shell is changed the lock screen, menu settings, background image (in the first Instance, it was white) and the notification bar._

    Lock screen allows you to add five additional main window, which can be positioned as shortcuts and widgets. Funny looks tracking the movements of the fingers, it looks like the sunbeams on the wall, the closer you hold your finger to the screen - the brighter the light beam. Unlike in the first instance, this unlock the screen can be as such as well as familiar with earlier versions of TouchWiz, that is, with a ripple effect and the corresponding sound. There is an automatic mode to unlock the screen, depending on your location.

    Desk still may include from one to seven windows, panel labels and from one to five applications. The interface works very smoothly, it's about as paging windows and move widgets and shortcuts. Reaction to the touch instant. Following the general trend, Samsung Galaxy S4 sensor capable of handling not only the touch of your fingers, but also other items, for example, you can type messages easily with gloves on.

    Notification panel can display five to eight switches in portrait and landscape mode, or all twenty-clicking on the icon in the upper right corner. If any of the labels are not visible on the screen, and have no desire to open all, you can browse to the left or right.

    The smartphone appeared more control over voice and gestures, display hints when you hover on a particular area of the screen and track the movement of the user's eyes. In emergency situations (set menu), the smart phone can take photos of yourself and the main front facing camera and send them together with data about your location to a specified number.

    Hardware Platform

    When in the beginning of the review, we said that Samsung smartphones have similar with other devices specifications, we slightly slukavili, Samsung Galaxy S4 - the first smartphone with a crystal with eight cores. System-on-a-chip Exynos 5410 Is made on 28-nanometer process technology and includes four productive core Cortex-A15 processor with a clock speed of 1.6 GHz, and four budget-core Cortex-A7 processor with a clock speed of 1.2 GHz. Looking ahead, we note that the application Antutu Tester, which we use in testing of autonomy, uses the maximum load of the processor and the maximum brightness of the screen. Therefore the results of the benchmark relatively modest when compared with other models. If you do not load the device at 100%, you can count on 88 hours of music playback, 12 hours and 40 minutes of reading at 0% brightness, 10 hours and 30 minutes of HD-video from Youtube at the same brightness and sound in the headphones for 12 of the 15 levels and 8 hours and 35 minutes at 50% brightness. Those who do not plan to actively load so your smartphone will charge the device every two, two and a half days. In this case, you do not have to turn off all the sensors, wireless modules, GPS, and switch to the operation mode in 2G-network, during which time you can listen to 2-3 hours of music, view about 30 minutes of video from Youtube, an hour to talk to other social networks and, of course, make phone

    Calls and send messages. The result is more than decent. There is hardly a device of this class that can beat Samsung Galaxy S4 on autonomy.

    System-on-a-chip Exynos 5 Octa Shows the best results to date performance in all the benchmarks. Only one new benchmark 3DMark, Galaxy S4 scored 4 points less than the Sony Xperia ZL, but such a marginal difference can be attributed to measurement error. Games, Full HD-video, and everything starts working smoothly. It is difficult to imagine that the ability to download 2 GB of RAM and four 1.6 GHz processor cores and three cores video. Built-in memory, depending on the configuration can be 16, 32 or 64 GB. To these we can add 64 GB by using memory cards and virtually unlimited when connecting USB-drives through the USB Host.

    Display

    In this device, Samsung has pioneered the use of Full HD-screen with a diagonal of 5 inches. For the first time in the display settings is possible to choose between "Professional Adobe RGB» or "optimized". In addition there are two new "Dynamic", "Standard" and "Invictus." They significantly affect the outputted image, which is later. In addition to these modes, there is an automatic adjustment of brightness depending on the image on the screen.

    Review Samsung Galaxy S4

    Brightness values are in the range of 7.23 cd / m 2 (Auto-tuning of brightness) to 323 cd / m 2 (self-tuning brightness disabled) in the "Dynamic". In Adobe RGB mode and the "film" does not exceed the brightness of 315 cd / m 2. Therefore, if you feel a lack of brightness recommend disabling automatic adjustment (not to be confused in the automatic brightness control), and select dynamic mode screen. But in cases where the minimum necessary brightness automatically adjusts better to include.

    Opponents of the bright colors of the display Samsung Galaxy S4 may not seem like much, bright when using the "Film", and, if possible, the minimum value of brightness. The higher the brightness is, the greater the displayed color will be different from the reference RGB. Similarly, the effect on the brightness of the color temperature and gray.

    See the work of the display modes "Professional" can be viewed below. If we do not take into account the bright colors, gray and setting the color temperature is almost the same as those shows Super AMOLED display in the "Film".

To date, the standard display Full HD-quality color display of the ones that we've seen, is set to Huawei Ascend D2, but if you are not committed to them most ardent right, you will not be disappointed screen Samsung Galaxy S4.

    The behavior of the display Samsung Galaxy S4 on a bright sunny day in no inferior smartphone Sony Xperia ZL and Huawei Ascend D2 , despite the fact that they are much brighter above. This helps in anti-glare substrate. Given the long-awaited arrival of sunny days, we had the opportunity to test the display in bright light. We never have any desire to increase the brightness, whether on camera or just reading the mail.

    Camera

    The Samsung understands that consumers are susceptible to numbers, so they did not use in his flagship ultrapikseli unclear, lack of which HTC are still being felt, and established 13 MP matrix Sony Exmor RS. Readers are able to evaluate the quality of shooting Samsung Galaxy S4 in the Roundup .Next week will be a comparison with a more serious camera phones - Asus Padfone2 and Huawei Ascend D2.

    The camera interface has been completely redesigned. Now for the photography or video recording does not need to switch to the appropriate mode, buttons for photo and video side by side with each other. Below them are the keys select the shooting mode, and above them - information on the current mode. In the lower left corner shows the thumbnail of the last photo or video. In the upper left corner there is the key to change the camera, running front-facing camera for simultaneous operation of two modules (photographs and videos recorded in this mode with the maximum resolution, unlike the LG Optimus G Pro, where the video is recorded with a resolution of 1280x720 pixels). Here is the call key settings. Its first press to select the flash mode, shoot in low light, turn off the microphone, specify the type of video recording and removable share content with friends, social

    Networks, or use a remote viewfinder. Repeatedly pressing a pop-up window with three tabs - photos, videos, and general settings.

    The speed of the camera, the convenience and the number of options is able to satisfy the most demanding users.

    The results

    Recall that this review is not the last data on the smartphone Samsung Galaxy S4. Separately, we consider the interface of the device and tell about their experiences after prolonged use Samsung Galaxy S4 as the primary means for communication.

    The new flagship of Samsung did not revolution or revelation, it is a logical development of the predecessor. In the new improved display and its diagonal, established 13-megapixel camera, advanced hardware platform, a larger battery, and the latest version of the operating system Android. All this suggests that this is a flagship without any discounts. He shows excellent time and

    Ergonomics, ample opportunities for setting the display, high performance, seamless and user-friendly interface. The recommended price of the smartphone is higher than HTC One, but lower than Sony Xperia Z and Sony Xperia ZL. Cost Huawei Ascend D2 is open to question, the expected time of appearance of the latter - the end of May. Closer to that time, and the price will be known. None of the devices supplied to nedotyagivaet Galaxy S4 for autonomy and performance, the version of the operating system and the smooth operation of the interface, but on the quality of the camera is not all that simple, why, you can learn from a comparative review. However, Samsung Galaxy S4 - it's the best device that will be available before the summer, and after it is unlikely there will soon be smartphones that can encroach on the superiority of the flagship Samsung.
